SECIFICATION forming part of Letters Patent No. 612,448, dated October 18, 18981. Application filed December 28,1896. Serial No. 617,201.- (No model.)

.To @ZZ whom t may concern:

Be it known that I, ROBERT S. WATSON, a citizen of the United States, residing at Bay City, in the county of Bay and State of Michigan,`have invented certain new and useful` arrangement, and construction of the various parts and elements which will be hereinafter more fully described in detail, and which will be specically pointed out in the claims of this specification.

One of the objects of the invention is to prozo vide a water-closet that may be regulated to liush the bowl with any desired amount of water when opened, and which will close when the desired amount of water has been discharged into the bowl.

Another object of the invention is to provide a water-closetl that will be cheap and durable in its construction and at the same time accurate, convenient, and simplein its operation. y

3o I attain these objects bymeans of the delvices illustrated in the accompanying drawings, in which the same iigures of reference will be found indicating the same parts or elements throughout the several views, and in which.-

Figure'l is afront View of a water-closet embodying my improvement. Fig. 2 is a vertical section of my invention,showing the valves closed. Fig. 3 is the same, showing 4o the valves open to iiush the bowl. Fig. 4 is an enlarged detail sectional view of the pneumatic regulating-valve.

1 represents the bodyportion of my improvement, composed of an upper cylinder 2, forming an air-chamber, and the lower cylinder'3, forming a water-chamber. The aircylinder 2 is providedV with a suitable top 4, having acentral opening and a suitable packing-box 5, through which opening and pack- 5o ing-box 5 is passed a hollow valve-stem 6,

which extends downwardly through the air- 4chamber 2 and through a suitable packingboX 7 on thedivision or partition 8, between the cylinders 2 and 3, and into the waterchamber 3, and this valve-stern 6 isV provided on its lower end lwith a valve 9, which engages with a valve-seat 10, located near the center of the water-cylinder 3.

11 is a piston located in the chamber2 and lsecured to the valve-stem 6, while 27 is a coiled spring with its lower end engaging with the partition 8 and with its upper end coming in contact with the bottom of `the piston 11, while 12 is an air-regulating valve tapped through the top 4 and into the chamber 2. As shown in Fig.`4, this valve is similar in construction to an ordinary check-valve, the valve 13 being held on the seat 14 by the coiled spring` 15, while 16 is an adjustingpin tapped through the framework 17 (which surrounds the valve) and with its lower end coming in contact with the valve 13 and preventing said valve` from entirely closing, so that as the pin 16 is screwed farther into the threaded openingin the framework 17 it holds the valve 13 farther from the seat 14, thus regulating the opening of the valve 12.

The valve 9 `is provided with a small central opening 18 and with lateral openings 19 in its sides above the seat 10, the part surrounding opening 18 forming a seat :for an auxiliary or relief valve 20, secured to the lower end of la valve-stem 21, which passes upwardly through the hollow valve-stem 6 and is tapped into a handle 22, while 23 is a coiled springhaving one end engaging with i the top of said hollow valve-stem 6 and with its opposite or upper end engaging with the handle 22 for holding the valve 2O on the seat surrounding opening 13.

24 is an inlet-pipe opening into the bottom of the cylinder 3, and 25 is an outlet-pipe located in the side of said cylinder above the valve-seat 10, while the cylinder 2 is provided with a series of transverse openings v26 in its side near the bottom of said cylinder.

The parts being in the position shown in Fig. 2, the inlet-pipe 24 is connected to any suitable water-supply, and the outlet 25 is connected to the bowl 28, which may be of any desired construction or pattern.

To iiush the bowl, the handle 22 is pushed downward, which first opens the relief-valve 20, allowing a sufficient amount of water to IOO pass through the openings 13 and 19 in the valve 9 to relieve the pressure, and the `handle then coming in Contact with the top of the hollow valve-stem 6 opens the valve 9, allowing the full pressure to pass through the chamber 3 and out of the outlet 25 into the bowl 23, while at the same time the valvestem 6 forces the piston 1l in the chamber 2 downwardly, displacing the air in said chamber below said piston through the openings 26 and, opening the regulating-valve 12, fills the space in the chamber 2 above the piston with air. As the force is removed from the handle 22 the spring 23 at once closes the relief-valve 20, while the pressure working against the bottom of the valve 9 begins to force the same upwardly. The air being confined in the chamber 2 above the piston 11 prevents said piston from rising, except as the air is allowed to pass out of said chamber through the regulating-valve 12. rlhe adjusting-pin 16 being screwed down to hold the valve 13 open the desired distance, the air in the chamber 2 is allowed to slowly pass out through said valve, which allows the piston l1 on the valve stem 0 to rise slowly and allow the valve 9 to close and again place the parts in their original positions.

If desirable to flush the bowl for some time, the adjusting-pin 16 is only screwed down a short distance to hold the valve 13 slightly open, allowing the water to pass through the valve 9 and into the bowl 28 for any desired length of time; but if it is desirable to iiush the bowl quickly (as where the water-pressure is great) the pin 16 may be screwed down far enough to open the valve 13 sufficiently to allow the parts to return to their original positions immediately.

It will be readily seen that a great advantage is gained over the common or wellknown manner of flushing a closet by emptying the water from a tank into the bowl, as the water generally used after standing in such a tank for a short time becomes stagnant and full of decomposed organic matter, which is a great disadvantage from a sanitary point of view, especially in dwelling-houses.

Another great advantage is gained where it is desirable to use water under great pressure, as the opening of the valve 2O relieves the pressure sufficiently to allow the valve 9 to open easily, and the spring 27 in the chamber 2, pressing against the piston 11, permits the parts to be easily returned to their original position.

I do not limit my invention to the precise form and construction herein shown and described; but

What I claim as new, and desire to secure by Letters Patent, is-

1. Thecoinbination in awater-closet, of the water-cylinder provided with ingress and egress openings at its opposite ends and with apartition containing an opening and avalveseat between said openings, an air-cylinder located above said watercylinder, a hollow valve-stem passed through said air-cylinder and into said water-cylinder and carrying a piston within the air-cylinder and a hollow valve upon its lower end for engaging with said Valve-seat and provided with transverse openings above said valve-seat and having on its lower end an opening for a valve-stem and a seat for a relief-valve, a valve-stem passed through said hollow valve-stem and provided on its lower end with a relief-valve for engaging with said relief-valve seat, a spring for closing said relief-valve, and a valve for regulating the egress of air from the air-cylinder above the piston, substantially as set forth.

2. The combination in a water-closet, of the water-cylinder provided on its opposite ends with water ingress and egress openings and a web containing an opening and avalve-seat between said openings, an air-cylinder above said water-cylinder and provided on its lower portion with side openings for free admission and egress of air therefrom, a hollow valvestem passed through said air-cylinder and eX- tending into said water-cylinder and provided on its lower end with a hollow valve for engaging with said valve-seat in said web and an end opening containing a seat and a relief-valve and having on its portion above said web a series of relief-openings, a valve-stem passed through and with its ends projecting beyond said hollow valve-stem and with its lower end secured to said relief-valve, a spring for closing said relief-valve, and a valve for regulating the ingress and egress of air from said air-cylinder above said piston, substantially as set forth.

3. In a Water-closet the combination of the water-cylinder containing a valve-seat 10, an air-cylinder located above said water-cylinder and provided with transverse openings near its bottom, a hollow valve-stem 6, passed through said air-cylinder and into said watercylinder and carrying a valve 9, on its lower end for engaging with said valve-seat and provided with a central opening 18, forming a valve-seat and lateral openings 19, above said seat l0, a valve-stem 21, passed through said hollow valve stem 6, and carrying a valve on its lower end for engaging with said valve-seat 18, in the valve 9, and on its opposite or upper end a handle 22, a coiled spring 23, engaging with said handle and top of said hollow valve-stem n6, an inlet-pipe tapped into said water-cylinder below said valve-seat 10, and an outlet-pipe tapped into said water-cylinder above said valve-seat 10, a valve 12, tapped into the top of said aircylinder to regulate the outlet of air in said air-cylinder, substantially as set forth.
